The time t required to drive a certain distance varies inversely with the speed r. If it takes 4 hours to drive the distance at 35 miles per hour, how long will it take to drive the same distance at 45 miles per hour?
about 3.11 hours*********
140 hours
about 5.14 hours
393.75 hours
4(35) = x(45) I agree with 3.11
All the answers are different so even if they did have the rest of the answers if you put his answers in you 'd fail
usually they are the same if youre on connections, otherwise you can figure them out on mathway or desmos graphing calculator.
do you have the rest of the answers for the test?

Anonymous was right,its 3.1 hours.
yes please
thanks if this is right yall, why does nobody learn that the math tests are always different lmao, they always are.
The time t required to drive a certain distance varies inversely with the speed r. If it takes 4 hours to drive the distance at 40 miles per hour, how long will it take to drive the same distance at 55 miles per hour?
Using the formula for inverse variation, we have:
t = k/r
where t is the time, r is the speed, and k is a constant of proportionality. To solve for k, we can use the given information that it takes 4 hours to drive the distance at 40 miles per hour:
4 = k/40
Multiplying both sides by 40, we get:
k = 160
Now we can use this value of k to find the time it takes to drive the same distance at 55 miles per hour:
t = 160/55
t ≈ 2.91 hours
The time, t, required to drive a certain distance varies inversely with the speed r. If it takes 7 hours to drive the distance at 55 miles per hour, how long will it take to drive the same distance at 65 miles per hour?
Using the formula for inverse variation, we have:
t = k/r
where t is the time, r is the speed, and k is a constant of proportionality. To solve for k, we can use the given information that it takes 7 hours to drive the distance at 55 miles per hour:
7 = k/55
Multiplying both sides by 55, we get:
k = 385
Now we can use this value of k to find the time it takes to drive the same distance at 65 miles per hour:
t = 385/65
t ≈ 5.92 hours
